The “27 Dresses” babe and her guy pal hit up Sephora, where Heigl grabbed some lipstick, before heading over to the Apple store to check out the new 3G iPhone, though they didn’t buy one.

Both actors looked casual-chic, with Katherine sporting a grey belted dress with a cream colored cardigan and matching brown leather handbag and boots, while Knight rocked a brown t-shirt and jeans.

On a related note, the “Knocked-Up” actress recently told press that she’s considering returning to her Mormon roots. "I'm not as disciplined about it was I once was, but I hope to find my way back as I get older and a little less selfish. I'm ashamed to say that I've just got very lazy about it. I satisfy my vices instead of fighting them."

But it would take some serious willpower. "If I start going back to church, I'd have to stop the smoking and drinking. And I wouldn't be able to curse anymore."
